Baby shower items

I have been invited to another baby shower and I always seem to make a blanket of some sort, wash cloths for the baby and then grab bath stuff to go with that.  I may put some diapers in as well.  But since I haven't had kids yet I'm never for sure what they really need.  I know the blanket is something that they can keep forever and can be a neat item to keep, but what else is good? Help me out all you mommies out there!
